预防大体积混凝土裂缝的控制措施及温度计算

Control measure of preventing the mass concrete crack and temperature calculate

介绍了避免大体积混凝土出现温度裂缝的措施及防止混凝土最高温度与表面温度不超过25℃,计算混凝土最高温度的方法;根据实测结果,提出了对掺有矿粉的粉煤灰大体积混凝土的最高温度计算公式调整意见并进行了验证,以便更好的为工程服务。

The paper introduce a series of measures to avoid concrete temperature cracks on mass concrete and methods to calculate concrete maximum temperature for preventing concrete maximum temperature and surface temperature from exceeding 25 ℃. According to measured result to make maximum temperature formula adjustments and the certification on the ash-slag mass concrete added mineral filler, in order to serve project better.
